26.9 Flash Memory Programming by Self-Writing
program. Because this function allows a user application to rewrite the flash memory by using the 78K0/Kx2 self-
programming sample library, it can be used to upgrade the program in the field.

The 78K0/LF2 supports a self-programming function that can be used to rewrite the flash memory via a user
If an interrupt occurs during self-programming, self-programming can be temporarily stopped and interrupt
Remark For details of the self-programming function and the 78K0/Kx2 self-programming library, refer to
Cautions 1. The self-programming function cannot be used when the CPU operates with the subsystem

2. Input a high level to the FLMD0 pin during self-programming.
3. Be sure to execute the DI instruction before starting self-programming.
4. Self-programming is also stopped by an interrupt request that is not masked even in the DI

The self-programming function checks the interrupt request flags (IF0L, IF0H, IF1L, and IF1H).
If an interrupt request is generated, self-programming is stopped.
